according to their site, the clavicula M3 mtb is 410g for the 12s boost with 34T chainring. Here's the xcx weights

what other cranksets have you considered that's a bit more affordable?

At this point, there are no alternatives I've found to be sufficiently appealing. It's either incolors or THMs, but the THMs break both the bank, and the "budget" theme of this build. The Campy SR cranks look great and i'm not sacrificing it for anything under a 200g+ weight savings.

When it comes to options, I guess the closest alternative would be a 3T torno crank with a custom-made chainring (330g + ~80g)

Thanks for the info on skypivot. I saw one on ebay a few weeks ago but it got snatched up pretty quick. I'll pass on THM for now. I'll probably get more bang for my buck spending $1200 towards a carbon wheelset.


Have a look at the carbon Aerozine Taiwan cranks.

These are 25g heavier (365g) than RED eTap AXS DUB (340g) and almost twice the price (465USD vs 233EUR). Even EC90 SL are marginally lighter (351g) and cheaper (354EUR).

What AE saddle/seatpost did you use? My set weighed like 250g IIRC. I've been meaning to cut my seatpost too

Here is the link to the seatpost if the link is broken, google "Elita One carbon seatpost aliexpress" and you'll find it.

Here's the link to the saddle too :beerchug:

compared to regular spokes they are a pain to build, mainly when it comes to lacing because of jow hard you need to pull to get the threads to bite. Length depends on rim and hub obvioisly, i think mine were 283 but i dont remember

The title probably sounds akin to some weight weenie oxymoron, but alas, here it is. It's certainly not done, but it's at least sub-5 now. As for "budget," I guess for the weight, you could call it a budget build.

I'll add some better full-bike photos when the lighting is good/I go out with my camera.

The next step in my journey towards practical weight weenie-ing is converting this to 1x. You may wonder, why go 1x11 50T on a bike that's perfect for climbing? To which I will answer, "find me a hill in Chicago please." :D

Plus, 1x is just more user friendly. The SRAM+Campag front shifting on this bike is utter GARBAGE. I never use the small chainring over concerns of it dropping the chain, and that's with almost no power.


The 1x setup will probably be this:

1. FSA Ceramic PF30 BB - 50g (-28g, 75USD)
2. InColor Skypivot Cranks + Spider - 327g (350 USD + shipping)
3. Fibre-Lyte or Lightworks (eBay) Carbon Chainring 50T (Both ~130 USD, Fibre-Lyte is well known, but Lightworks has a narrow-wide version which Fibre-Lyte doesn't) - 60g
4. KCNC Short Chainring Bolts - 6g
5. Total Crankset weight = 393g (-232g)
6. Remove FD+Chain Catcher + Hanger + Bolts (-99g)
7. Remove FD Shift Housing + Cable + Barrel Adjuster (estimated -35-40g)
8. Remove Shift Paddle + Ratchet Internals from Red Left Shifter (estimated -30g)
9. PYC SP-1101 Chain (-14g)

9. Estimated 1x Savings: ~439g, meaning the new goal would be 10lbs, of course :D

Now for the gallery :beerchug:

White spokes are pretty eyecatching!

Image
Get pretty scared every time I work on this stem... plus, the printed manual I received when I bought it says 3Nm for the HB-Clamp, now they updated it to 2Nm on their website... Always did 3Nm, am I in danger? :unbelievable:

Image
Image
I hate the "new ergo" brake lever instructions FSA gave. They looked like shit and the hoods actually pointed slightly down when done according to their "optimal mounting position." Straight in the bin it went.

Image
These poor Ciamillo brakes from 2006... They barely open wide enough for these 25mm rims. I get bare minimum brake lever travel even with the tire release tab flipped to the "open" position.

Image
Some heavy tuning was done on this saddle. It was bare carbon to start at 82g, ended up at 62g.

An aluminum mini brake noodle was used to shorten the RD cable run. The frame was also designed to have the housing run all the way to the bottom bracket cable guide, but a 4mm-5mm stepdown ferrule was used to create a DIY cable stop, along with some inner sheathing to protect the frame innards from cable abrasion.

Can't wait for the 1x conversion!
Hello!
I fell in love with your bike.
Please tell me how long you skate and how long will one star be enough for you? I have the same (or very similar, like yours. I remember when I rode my bike 90-100 miles every day for several months (3-4), then they fell into disrepair and had to be replaced with new ones.

Ok so how have i missed this all along? Taking out the stupid "stealth rings" on the red cassette saves almost 7g for free. and the best part is: the bike is still silent.
